INTRODUCTION An urban forestry progra~ can provide ser%,ices such as recomme~da=ion of planting materials for homeowners, commercial areas, land city parks; answering calls ~rom homeowners about various tree and shrub problems; working with developers and builder~ to minimize construction damage to trees. The e~ecti~eness of these seN, ices can be improved with the knowledge of the ~verall cover type of %he city. This report provides this information. The Cit~ of Ramsey encompasses 28.82 square males or 18,449.!1 acres according to the 1979 report. Total wooded acres is 4726.56 acres om 25.61 percent of the ci=y. This report examines areas covered ~ith trees, including rural and residential. This report assumes ~hat the ~orest cover in each type is nol-mal!y distributed. Aerial photos were used ~or the initial delineation of the city. Sine typ~s were identified: vacant, water, primarily Red Oaks, primaril~ Bur Oaks, mixed tree species, scrub oaks, not oaks, bottomla~d species,- and Spruce/Pine. Using this information the number a~d percent of acres of each type was calculated (excluding vacant a~d water,) see Table I. Aerial phptos provide valuable info~-mation which we ~urther used to conduct a~cround check. Using stratified random sa~p!ing increased accuracy i(',/- 10% at 80% confidence level) since there is knowledge about thei population. In sa~p!ing, we set up strata according to the majo~ ~orest t~pes, made separate sa/~ple estimates Jot each rype,then~combined the r.vpe data to give an estimate ~or the entire PoPulation. The boundaries and total acreage of each type are )Lnown. using propo_-tio~a! allocation the number of saddles taken ~or each typ_e is made e~.ua! ~o the propor~ion cf all ~its in the Dopu!ation which ~a!~ in that u.vpe. The total number of plots taken were 30. The data ~rom these points were e~trapoiated to estimate the tree ~DoDu!ation. and characteristics ~or the cover t.~pes Each cover ~.vpe was proportionally inventoried for regeneration, see Table ~77 Two of the cover z~vpes, s~=uuD oak and not oak, were inventorie~d. ~or receneration.~ The area encompassed~ by these tvDes._ are vo~ung ~thus~ an area of receneration, is not possible =~ this time. The %able lists the prima~-y tree species and'the total n~ber of stems ~¢ounted. !n addition to the primar~ tree species, understo_~y'sDecies were recorded but,~ere not tallied.
